Question about LS400 Service History "EPA WASTE REMOVAL"

What does this mean in my ls400 service history obtained from Lexus Drivers.com? Does anyone know what a "EPA WASTE REMOVAL" is?? Also, does all this body work indicate that my car was in an accident at one time way back in 1997? Car fax comes out clean so if it was ever in an accident, I think it went unreported.
